Biofuel crops are being considered as an option for reduction of global warming.  However, biofuel crops are not 100% carbon neutral.  There are three agriculture related greenhouse gases: carbon dioxide, methane, and nitrous oxide, N2O. Nitrous oxide is an important greenhouse gas that is often overlooked by the non scientific community.  60% of nitrous oxide emissions are produced by agriculture ecosystems.  Input of fertilizer greatly stimulates nitrous oxide emissions.

At the conclusion of the lesson, students will be able to:

  • Describe certain processes in nitrogen cycling (specifically, denitrification, nitrification)
  • Understand that an increase in fertilization of biofuel crops will increase the release greenhouse gases
  • Know how nitrous oxide can counteract the greenhouse gas reduction effects of using biofuels as a means of reducing greenhouse gas emissions
